Starter motor wont start, clicking noise, new battery

Hi maybe somebody could help:The bike failed to start the other day and just made a clicking noise. I bump started it and it started again afterwards fine. Sometimes it started and sometimes it didnt. Maybe a dodgy battery i thought so I bought a new Exide YTZ10-bs and filled it with acid and charged it up just now. The bike went totally dead and wouldnt even click when i fitted it (I think this is because I disconnected the two wires that run next to the terminal wires) . There is a datatool alarm that may have run out of power and disabled the bike. So I bump started it and now all the lights horn alarm etc work and it makes the clicking noise when trying to start but it still wont start!Anybody have any ideas? The battery terminals are clean.

the clicking is your relay so that's okay. Is it clicking lots as you hold in the start or just once?

Give your starter motor a decent whack with a hammer and see if that sorts it for a while, if so schedule pulling it and performing an overhaul. Order a gasket before you pull it out as you'll need one when you put it back in.

My understanding is that if it clicks repeatedly it's your starter motor (don't let it click repeatedly or you'll burn out the relay)

and if it just clicks once, it's the starter relay.

I would double check the charging system is good as I have just had a starting issue and it was the battery not holding charge.

Do you have access to a multimeter?

If yes: with the bike running and lights on - attach positive to + and negative to - on the battery - take a reading (multimeter to 20V). Rev the bike to 5000rpm and take a reading. report back (should be 13~13.5 then 14.5)

If no: start the bike (jump if necessary) and put the lights on. put it on it's stand and put your hand over the headlight, or stand looking at it. Give the bike some revs, does the light get brighter beyond 5k ? If yes good, if no charging problem.

It is either the regulator/rectifier (fried and not changing the current for the charging system - a common problem but not difficult or expensive)

the stator or generator - unlikely but not impossible - okay to sort if you're handy with tools.

the battery - you've just changed it so we'll assume that's good.

If the charging system is fine:

Starter motor will need wire brush internals checked and perhaps renewed. I've not done this but it looks easy to get at, and I think you'll get plenty of help on here, just remember to buy that gasket, there's nothing worse than unnecessary time off the road!! (always sunny!!)

First off is your battery charged up? it could be getting old. If you do lots of short journeys it's going to get depleted. Well I am just going to leave my motor for the moment, it is working so i dont want to mess around with it. What about the refurb kit you were talking about?

A couple of working starters on ebay sub £30 but wemoto.com do new brushes so i'm planning on refurbing my unit just for the sake of learning more. Can someone point me in the direction if a new o-ring or gasket for the starter motor before i remove it, cant find one anywhere!!
